Things Have Changed – Sort of

The last few weeks highlighted the need to bring a new understanding of, and strategy for, investment risk. Volatility is increasing and occurring over a significantly compressed timeframe – for individual stocks and the overall market. Recent trading activity in GameStop, AMC, and a few other stocks demand an investment strategy focusing on Risk Adjusted Return. The new power of retail investors is here to stay, and that will shake up traditional portfolio managers because they are increasingly losing control of the trading process. Trading apps on platforms like Robinhood and social media chat rooms found on Reddit are game changers, fueling an unprecedented level of interest and activity (social media information is easily accessible and trading activity has very little friction – few, if any fees, and immediate). These two factors are irreversibly changing the market. In the past year, U.S. brokers added at least 10 million new retail trading accounts, and a shift to zero trading commissions late in 2019 unlocked a wave of activity that dwarfed even the wild days of the dot-com bubble. Beginning in early 2020, and coinciding with coronavirus lockdowns, trading activity started to surge and has not subsided, even as the economy has gradually reopened. Average daily trading at the biggest retail brokers hit a record of 6.6 million a day in December 2020. In January 2021, it reached 8.1 million. On January 27, 2021, equity volume was triple the average day in 2019.Retail investing has been a small fish trading in the large hedge fund and institutional pond. But that’s changing. Before the pandemic, retail trading made up about 15% of equity volume; now, it’s consistently making up more than 20%. The game changer is when that activity is concentrated on just a few stocks, a much more likely event among retail investors (driven by social media platforms), and it makes a substantial difference. In the case of GameStop and several other highly shorted stocks, it can cause startling price movements in a very short time.
